The 300-carat necklace thought to be at the center of the infamous 'Affair of the Diamond Necklace' that contributed to the French Revolution sold at auction in Geneva, auction house Sotheby's said Wednesday,

The necklace containing around 300 carats of diamonds was bought by an unidentified woman who put in her bid over the phone, Sotheby's said.

"There is obviously a niche in the market for historical jewels with fabulous provenances," Sotheby's jewelry specialist Andres White Correal said after a diamond-studded necklace with a possible link to Marie Antoinette's downfall sold for more than double the pre-sale estimate.
